Heptagon Medallion

Two heptagons (7-sided polygons), an outside shell and an inside star, are created and will be combined into one heptagon medallion. Precut printed duo papers will be provided for this session, and the attendants are required to make precise scoring along the diagram lines in order to produce perfectly symmetric patterns. The output can be laminated to be used as a coaster. Bring a ruler and a ball point pen for scoring. Fine to medium width is preferable.
